Abstract

Flatfish species are characterized by morphological changes from larvae to juvenile (symmetry to asymmetry with one eye migrating to the other side). The present study collected a total of 137 specimens of flatfish (larvae and juveniles) from the bank waters of the Kalong and Tien Yen estuaries in Quang Ninh province from 2013 to 2015. The specimens were identified to 5 species belonging to 3 families. They are Pseudorhombus arsius (D:75, A:56, C:18), Tephrinectes sp. (D:47, A:36, C:18), Brachirus orientalis (D:63-65, A:46, C:18-19), Solea ovata (D:59-63, A:44-49, C:17-19) and Cynoglossus sp. (D:98, A:73, C:10, V:4). This report gave diagnosis, described morphology and built a dichotomous key of larvae and juveniles of flatfish collected from the study area.
